Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Multi-modal Sensory Feedback System for Upper Limb Amputees

Christian Enz, Claudio Bruschini, Huaiqi Huang, Tao Li, Jörn Justiz

Providing sensory feedback for myoelectric prosthetic users can not only increase the manipulation ability but can also introduce a feeling of embodiment. Previous research has demonstrated the feasibility of providing mechanotactile or vibrotactile feedba ...

EMG Pattern Recognition Using Decomposition Techniques for Constructing Multiclass Classifiers

Christian Enz, Claudio Bruschini, Huaiqi Huang, Tao Li, Jörn Justiz

To improve the dexterity of multi-functional myoelectric prosthetic hand, more accurate hand gesture recognition based on surface electromyographic (sEMG) signal is needed. This paper evaluates two types of time-domain EMG features, one independent feature ...

Automatic Hand Phantom Map Detection Methods

Christian Enz, Claudio Bruschini, Huaiqi Huang, Tao Li, Jörn Justiz

Many amputees have maps of referred sensation from their missing hand on their residual limb (phantom maps). This skin area can serve as a target for providing amputees with tactile sensory feedback. Providing tactile feedback on the phantom map can improv ...

Sensory Feedback for Prosthetic Hand Users

Christian Enz, Huaiqi Huang, Tao Li, Jörn Justiz

The proposed project targets the restoration of a natural sense of touch to persons using hand prostheses. Current myoelectrical upper limb prostheses normally lack tactile feedback, which limits their functionalities and user acceptance. This work propose ...

Data fusion for a hand prosthesis tactile feedback system

Christian Enz, Huaiqi Huang, Tao Li, Jörn Justiz, Ozan Unsal

Current myoelectrically controlled hand prostheses normally lack tactile feedback, thus limiting their functionalities and user acceptance. We propose a non-invasive tactile sensory feedback system, consisting miniaturized sensors, wireless communication m ...

With applications to the periodontal ligament: a nonlinear large strain viscoelastic law

Jörn Justiz

The soft tissue, called periodontal ligament (PDL), that connects the alveolar bone and the tooth root accounts to a large extent for the mobility, stress-distribution and, due to its viscoelastic properties, damping of the bone-tooth complex. The accurate ...
